Gunners boss Arsene Wenger will leave a decision on whether or not to field fit-again defender Thomas Vermaelen at left-back to the last minute.

Nacho Monreal (ankle) and Kieran Gibbs (gluteus) both remain doubtful, and if neither make it back in time for the Potters clash, Wenger could deploy Vermaelen, fully recovered from a shin problem, on the left of his defence.
